LAUNCHXL-CC3235SF: ImageCreator not loading via UniFlash, SLImageCreator errors from CLI

Will Castelnau

Part Number: LAUNCHXL-CC3235SF
Other Parts Discussed in Thread: UNIFLASH, , CC3235SF, CC3100, CC3200

Hi folks,

I am unable to load ImageCreator and tried both UniFlash 5 and the recently released v6.0.0.

When I select LAUNCHXL-CC3235SF from UniFlash, I get a spinning icon next to "Start Image Creator" as depicted in the attached pic.

If I attempt to start ImageCreator from the CLI, I get:

<uni flash root dir>/simplelink/imagecreator/bin/SLImageCreator

Traceback (most recent call last):
File "SLImageCreator.py", line 33, in <module>
File "/private/var/folders/79/10c7185s6cn_8zc1hsk5rcdw0000gn/T/pip-install-Um7Hyj/pyinstaller/PyInstaller/loader/pyimod03_importers.py", line 396, in load_module

File "weakref.py", line 14, in <module>

I am running this on MacOS.

What am I doing wrong?

Will,

I can reproduce this if I select the serial interface. If I select to use the onboard XDS110 then the issue does not occur. It also does not happen for me in UniFlash 5.1.

Are you able to use the XDS110 connection for now?

Select the CC3235SF device with "on-chip" beside it.

Regards,

John

Thanks John,

Yes you are right, but I think this doesn't launch ImageCreator?

I am in essence attempting to load user files onto this device as per the instructions here. Although the documentation suggests a specific version of UniFlash, it appears CC31XX/CC32XX are only supported in an ancient version of UniFlash: https://processors.wiki.ti.com/index.php/CCS_UniFlash_v3.4.1_Release_Notes#System_Requirements

Yet I have tried to install this specific version on Ubuntu 20.04, 18.04, 16.04 and 14.04 with zero success, and getting a core dump:

Can you clarify please? How do I upload user files into specific folders onto this device (root CA, private key, pem)?

Thanks.

Will,

CC3235SF is supported by the latest UniFlash. For CC3200 and CC3100 you would need to use the old 3.4.1 version.

If you use UniFlash 5.1 does image creator launch ok? On my mac when I click on the Start Image Creator button in UniFlash it comes up ok.

5.1 can be downloaded from here:

http://software-dl.ti.com/ccs/esd/uniflash/docs/release_archive.html

I am going to need to loop in the team that supports image creator.

John

I could not get ImageCreator to work, neither with UniFlah 5.3.1 or 6.0.0, equally GUI or command line as per original post.

It has been a process of trial and error, mostly error, I got ImageCreator to work by trying UniFlash 4.6.0 which has finally allowed me to load the User Files I needed onto the CC3532SF board I have.

Can you advise what the cause of the python stack trace is and as to why ImageCreator does not load as per original post?

Regards,
Will.

Will,

The ImageCreator team is looking into it. Can you check your python version for me. Just type python in a Terminal window and it will show the verison. I have provided them with my version but it would be good to check yours as well.

John

Thanks John,

Both Python 2.7.14 and 3.7.4 are installed, I tried starting SLImageCreator from the CLI by altering alias and paths to point to these versions separately, no joy.

I also created a separate python virtualenv to start SLImageCreator into manually on each version above, no joy.

Regards,

Will.

Will,

I have an updated version of Image Creator that for me resolved this issue on my Mac. I am going to send you a friend request so that I can send you this verison via private message. It would be great if you can give ths a try.

I am running macOS Mojave (10.14.2), what are you on?

Regards,

John
